He pleaded with Americans to be patient as the pipeline company returns to full operations.
"I want to be clear -- we will not feel the effects at the pump immediately," Biden said in remarks from the White House and carried on national television. "This is not like flicking on a light switch. This pipeline is 5,500 miles long."
Biden said that he expects to see a "region-by-region return to normalcy" starting this weekend and into next week, but told Americans not to be alarmed or hoard gasoline and warned against price-gouging.
"Don't panic,” he said. "I know seeing lines at the pumps or gas stations with no gas can be extremely stressful. But this is a temporary situation. Do not get more gas than you need in the next few days … Panic buying will only slow the process."
The president has been briefed on the incident every day since the attack happened last Friday night by his counselor Steve Ricchetti and National Security Council chief of staff Yohannes Abraham, a source familiar with the matter told ABC News and first reported by Axios. Biden was also briefed by White House National Security Adviser Jake Sullivan twice on Sunday and again on Monday and Tuesday.
In sign of the political sensitivities involved, the sources made a point of noting it was clear from Biden's first briefing that he wanted to be regularly updated on the latest developments and, in particular, what was being done to respond.
Colonial Pipeline restarted its system late Wednesday and in a statement Thursday morning said it's "made substantial progress" and that "product delivery has commenced in a majority" of markets they service in the southeast.
However, Energy Secretary Jennifer Granholm stressed it will still take time for all the effects of the hack to wear off.
"People will start to see normalcy in the next couple of days," Granholm said on CNN Thursday morning. "Hopefully by the end of the weekend, the consumer won't even know that the shortage exists anymore."
Until the shortage lets up, Granholm warned that hoarding supplies will only make things, and the prices at the pumps, worse.
"When hoarding happens, it compounds the problem. It exacerbates the lack of supply. And it may also contribute to gas price increases. So we want to make sure that everybody knows that this is going to be -- the situation going to be back to normal. No need to do that.”
In South Carolina, North Carolina, Virginia and Washington, D.C., gas stations with fuel outages are over 50%, according to GasBuddy, and for the first time in 7 years, gas prices nationally crossed $3 a gallon on Wednesday.
There are few things more politically dangerous than high gas prices, and with the Memorial Day holiday around the corner, the president is looking to tamper worries with his remarks and speak directly to frustrated Americans, making the case that this should be a short-lived issue.
His remarks came just hours after he signed an executive order to strengthen U.S. cybersecurity defenses with the goal of preventing similar attacks and after the White House has faced questions about why it wasn’t better prepared to protect its infrastructure.
Biden’s order mandates private companies "doing business with the federal government" share information with it about hacks.
"We pushed the authority as far as we could," a senior administration official said. “Anybody doing business with the U.S. government will have to share incidents, so that we can use that information to protect Americans more broadly."
It will also require all software bought by the federal government to meet certain security standards within nine months and "creates a pilot program to create an 'Energy Star' type of label so the government – and the public at large – can quickly determine whether software was developed securely."
Another danger the Biden administration is now confronted with are concerns over inflation and rising prices on consumer goods.
Prices consumers pay for goods like food and gas went up 0.8 percent in April according to the Bureau of Labor Statistics. Over the last 12 months, the “all items index” increased 4.2%., which is the largest 12-month increase since September 2008. Prices for used cars and trucks rose 10% in April as well, making it the largest 1-month increase since the series began in 1953, and were a significant contributor to the broader increase.
All three major stock indices fell Wednesday as data indicated inflation was higher than expected in the month of April and investors seem to be nervous that it may be higher and more persistent than the Federal Reserve and Treasury Secretary Janet Yellen have been forecasting.
White House press secretary Jen Psaki this week said that the administration takes "the possibility of inflation quite seriously" but that there are "a range of factors" in play.
"There’s a couple of data points that are specific to this moment. And we knew, just as the — as the economy, sort of, shrunk and shut down, that, as it’s turning back on, there would be some of these impacts."
